FAQs: Fawley

Would you work within a site like Townlands Memorial Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Fawley off your patch?

No. Places such as Fawley are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Do you use silicone for external joints?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Some joints call for hybrid, PU or polysulphide instead.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Do you replace failed glazing units?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, such as perimeter joints where frames meet the structure.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

How much does the work cost?

It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.

How we handle facade sealing in Fawley

Sealant around windows, doors and cladding panels stops rain reaching the wall behind. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on window and door perimeters, coping and flashing joints and shopfront frames, and the usual reasons a site gets in touch are water coming in around window frames and old perimeter mastic that has dried out. Facilities teams, main contractors and managing agents in Fawley tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Construction in and around smaller places such as Fawley is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Facade sealing in Fawley: the local picture

Fawley sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. Fawley is about 35 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

Older buildings in the area around Fawley, such as Greenlands, 1.2 miles to the south-east of Fawley, need care when sealed: the product has to suit soft or historic materials.

Fawley is about 6 miles west of Marlow, in Buckinghamshire. Across the RG9 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Across Buckinghamshire, 308 places are covered, including Fawley. Sites around Reading have their own page, about 9 miles away.

Sites close to Fawley are covered too, including Fawley Bottom (1 mile west), Middle Assendon (1 mile west), Lower Assendon (1 mile south-west), Bix (2 miles west) and Henley-on-Thames (3 miles south).

What the job involves on each surface

Precast concrete panels

Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported.

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint.

Our process

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Rural sites near Fawley may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Share the asbestos register for older buildings
  • Have the specification and drawings to hand
  • Tell staff and tenants when we’ll be in

Maintenance after handover

For the best life from the joints:

  • Never let anyone seal over old sealant
  • Keep sills, gutters and drainage paths clear
  • Report water ingress at frames as soon as it shows
  • Record the product and colour used on each elevation

Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly with a compatible product.

Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in.

Do you need facade sealing in Fawley?

Adhesive failure, where the sealant peels away from one face, normally comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and the joint opens with the first real movement.

It’s worth sending us details if you spot any of the following:

  • Perimeter joints where frames meet the structure
  • Gaps between rainscreen or cladding panels
  • Air leaks through failed facade joints
  • Unsightly perimeter sealant on a visible elevation

Hospital estates such as Townlands Memorial Hospital, 2.4 miles to the south of Fawley, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

How to choose a sealant contractor

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Damaged frames that need replacing
  • Installing or repairing glazing systems
  • Providing access systems for the work

Not sure which it is? You can ring 01277 525 020 or use the quote form and we’ll tell you honestly.

Joints and surfaces we work on

  • Shopfront frames
  • Coping and flashing joints
  • Stone and brick facade joints
  • Window and door perimeters
  • Perimeter joints where frames meet the structure
  • Cladding panel joints

What happens if it’s left?

Scaffold or access already on site makes resealing much simpler. Coordinating facade sealing with other external works avoids paying for access twice, which is often the biggest saving. Older rural buildings around Fawley move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.

What you get with us

  • Failed material removed, not covered up
  • 12-month guarantee on workmanship
  • Colour agreed before work starts
  • One number for every site we cover
